Application filed November '29,, 1918. Serial No. 784,101.

- To all whom it may concern:

. of the casing.

-5,-is a side view showing the chain Be it known that I, FREDERTC BARR, a citizen of the United States of America, and residing at New York, in the county of Kings and State of New York, have invented new and useful Improvements in- Pull-Sockets, of which the following 18 21} 1 ofthe shell. This portion 6 is made parspecification.

My invention relates particularly to the guiding and insulating the.

construction for chain.

In constructions of this character the switch mechanism is carried by an insulating body which is removably mounted in a shell or casing. The mechanism is operated by the chain which passes through one side The main object is to provide a simple and inexpensive form of chainguide which can be readily attached or detached from the shell sothat the parts can be readily assembled or disassembled when desired.

Another object is to provide the combination in a construction of the-character just described of means for insulating the chain and locating the parts so that the two parts of the shell-may be readily attached and yet.

are held securely together and may be readily detached.

Another object securely in position.

In its preferred form the invention contemplates a shell formed in' two parts with telescopic interlocking means and a slot in one side of one part of the shell together with a chain guide having a projecting bell and a. base plate with lugs for securing it to I the shell. The switch mechanismis carried by an insulating block and surrounded by insulating fiber which is'cut away-only at a point adjacent the chain guide and ad acent the interlock.

the block separate. Fig. 3, is a side view an partial section through the chain guide. Fig.4, is a fragmentary horizontal section through the chain guide. 1 e,

I is aside elevation showing the i I the body of the shell and'the insu ating block being assembled. Fig 6, is a perspective view of the chain guide detached.

The shell is in two parts, the body 1 telescoping with the cap 2. These parts are is to hold the cl m guide by a suitable insulating1 provided with suitable interlocking devices as for instance, a projecting loop 3' and a tongue 4 for preventing longitudinal separation, one edge of the loop 3 coasting with the shoulder 5 opposite the tongue 4.- for pre venting relative rotation. The loop 3 is carried by a resilient portion of the body ticularly resilient by reason of the slot 7 and the slit The switch mechanism may be of any suit able type and provided with a pull cord or chain 9 as it is customarily called. The

slot 16 is provided at the lower end of the 5161315 for the lug 13 so as to prevent lateral displacement of the chain guide at the bottom. Preferably the shell is bossed out at 17 to form a recess in the rear for the lug 13. I also preferably boss out the wall of the shell at 18 to provide freer play for the chain 9. v

The switch mechanism proper is carried stance of porcelain and t is is provided with a-lug 20 which projects into the slot 7 above the edge of the chain guide base plate 10. The insulating block 19 is surrounded by a layer of fiber 21 inside the shell, which fiber is cut away enoughto permit of the passage of the chainand also to permit easier compression of the shell part 6. It will thus be noticed that the chain is guided in a channel 22 in the block 19 within the fiber 21.

To assemble the parts the insulating block and switch mechanism (not shown) is inserted in the body 1 of the 'shell and the chain guide is placed in position as shown in Fig. '5, the edges of the base plateoverlapping the edges of the slots 15 and 16, the lugs 12 being in position to engage the shoulders 14 and the lug 13 being in position to engage beneath the boss 17. When the insulating block 19 is pushed downward, the lug 20 engages the upper edge of the chain guide base plate and pushes the base block 19 for in-' plate into position. The boss and cap of the shell may then be telescoped and interlocked.

While this construction requires only a minimum amount of metal and is easy to make and inexpensive, nevertheless the construction is sufiiciently strong to withstand commercial usage and may be readily attached or detached when desired. Furthermore, it is held from twisting or displacement and the chain is housed within the insulating block 19 inside of the fiber 21.

What I claim is 1. In apull socket switch, a shell body A having a slot, a chain guide having a base plate fitting. around outside the walls of theslot and having lugs fitting within the edges of the slot and arranged so as to prevent lateral displacement, a switch carrying block having a lug projecting into said slot and overstanding said base plate said Letters Patent.

- [SEAL] slot inside said shell and a switch carrying insulating block having a lug overstanding the edge of said base plate and a cap surrounding the edge of said shell body and said lug.

1. A pull socket comprising a shell having a slot with a shoulder and an extension slot and a chain guide having a base plate fitting the, outside of said shell with a lug at the end to engage said shoulder and a lug at the opposite end to engage inside said shell at the end of said extension slot.

5. A pull socket comprising a shell having a slot with a shoulder on each side and an extension slot, and a chain ide having two hooked lugsbent inwardi to engage said shoulders and a third lug engaging inside the shell beneath said extension slot and means for holding said chain guide in place.

6. A pull socket comprising a shell having a slot with a shoulder on each side and an extension slot with a recessed boss, and a chain guide having two hooked lugs bent inwardly to engage said shoulders and a third lug engaging inside the shell beneath said recessed boss.
